Halogens occurs naturally as salts; an exception is HCl from volcanoes.
Yes, the halogens did occur in nature as free elements.
in there native state
Also other elements can be involved.
94 kinds of atoms occur naturally on earth
"Synthetic" could be another word for something that does not occur naturally.
Halogens naturally occur in the gaseous state. Examples of halogens are fluorine, chlorine, bromine, iodine, and astatine.
Yes, the halogens did occur in nature as free elements.
group 17 elements (halogens)
The halogens are not found naturally in the earth's crust as pure elements because of their extreme reactivity. Because the halogens are close to having completely filled electron shells, they will often react with other substances in order to gain an electron. As an especially noteworthy case, fluorine is the most reactive of the halogens (and elements in general), and will even react with glass. Therefore, the halogens are found naturally as compounds, not pure elements.

Yes, radio waves occur naturally in the environment as a form of electromagnetic radiation.
Hexane is a nonpolar solvent that helps extract nonpolar compounds, such as halogens, from an aqueous solution. By adding hexane, the halogens will preferentially dissolve in the nonpolar layer, allowing for easier separation and purification of the halogens from the aqueous solution.
